Web Service Call Pure Path

I have DT 4.1 running monitoring IIS 6 instance of an application. Everything is setup on .NET 2.0 and higher.

I have Web service A and Web Service B. I call into Web Service A as this is our custom code to extend a product. Web service A also will make calls to Web Service B to get information or to do change request against data. Each web service is hosted in its own W3wp process or application pool for IIS.

I have different agents mapping as the Web Services could be called independently but if I call from Web Service A the Pure Path looks as if the path stops at Web Service B communication and waits for a reply.

I have HTTP tagging, Web Service tagging enabled on both agent mapping groups. Also have Web Service start new pure Path. Do I need to turn on .NET thread Tagging as well?

Does this mean you do not see any PurePath that actually makes a call from A->B? Do you get an extra PurePath for the calls into B that are made from A?

You should definitly enable .NET Thread Tagging as it is very likely that these web service calls are executed on different threads. In case there is no good reason why you have it disabled please enable it again
